Abstract:
... CMS (cytoplasmic male sterility) can be controlled by the mitochondrion genome in higher plants, including Satsuma mandarin. Somatic fusion experiments in citrus combining embryogenic callus protoplasts of one parent with leaf protoplasts of a second parent often produce cybrid plants of the leaf parent, a phenomenon occurring most often with interspecific fusion combinations. In an attempt to pra ...

Abstract:
... The antiproliferative effect of an immature Citrus grandis Osbeck fruit extract was investigated using U937 human leukaemia cells. Maximum cytotoxicity was observed using the hexane fraction (HF) of the extract. Cell death was dose-dependent (IC ₅₀ =ca. 60μg/ml) and was characterised by chromatin condensation, apoptotic body formation, and DNA fragmentation. The induction of apoptosis was confirme ...

Using GC-FID/MS and gas chromatography-olfactometry (GC-O), 50 and 47 aroma-active compounds were identified in pink and white pomelo peel extracts, respectively. The potency of each odorant in both pomelo peel extracts was determined by aroma extraction dilution analysis (AEDA). On the bas ...

Abstract:
... Ten Citrus (Linnaeus, 1753) species of North-East India have been karyo-morphologically analysed. All studied species had 2n=18 chromosomes without any evidence of numerical variation. All the chromosomes were found to be of metacentric and sub-metacentric in all the species; the morphology of the chromosomes showing size difference only. Symmetrical karyotype which does not have much difference i ...

C. sinensis was more tolerant to aluminum (Al) than C. grandis. Phosphorus (P) alleviated the toxic effects of Al on seedlings. Under Al stress, P increased root Al, but decreased shoot Al; C. sinensis accumula ...

Abstract:
... The aim of this work was to provide a set of mitochondrial markers to reveal polymorphism and to study the maternal phylogeny in citrus. We first used 44 universal markers previously described in the literature: nine of these markers produced amplification products but only one revealed polymorphism in citrus. We then designed six conserved pairs of primers using the complete mitochondrial DNA seq ...

Nutrient management, together with other cultural practices such as pruning and irrigation, for mitigation of the disease has been practiced in China for many years. Our literature review, field survey, and inte ...

Abstract:
... Fire blight (Erwinia amylovora) was first observed on apple trees in 1992 in Pitesti (Maracineni) and Braila counties of southeast Romania. Due to several factors, including climate, underestimated loss and lack of efficient control measures, the disease spread to 42 counties in Romania by the year 2000. From 2004 to 2006, 34,785.3 ha (46% of cultivated areas) were inspected for fire blight occurr ...
